Hi all. Ok, so when my alarm was set off there would be no noise, just the indicators flashing (00134 diagnostic error code). I replaced the H12 alarm horn yesterday with another second hand one (same part no.) but now the alarm doesn't work at all plus the 5amp fuse blew and keeps blowing when I replace. I'm now also getting 2 further diagnostic errors for the interior monitoring sensors (01135) and inclination sensor (00323). Help!
